To all whom it may concern:

Be it known that we, TrroMAs K. DIXON, ALEXANDER KLEIN, Jnssn C. Gore,and Gnome R. GHENT, citizens or" the United States, residing at Houston,inthe county of Harris and State of Texas, have invent ed certain newand useful Improvements in a Transfer Adding and Totaling Machine, orwhich the following is a specification.

This invention relates to new and useful improvements in a transferadding and totaling machine. v

Une object of the invention is to'provioe a machine of the characterdescribed which has been specially designed for the purpose ofmechanically transferring the totals registered on adding machines, tothe totaling machine whereby a register is made the grand total of theamounts indicated by the different individual addingmachinesv Themachine herein described is particularly useful in connection with ourmechaniof keeping a cal store described in our application for patentthereon, filed in the United States Patent Office on the 7 day of June,1921, under Serial No. 475,629, for the purpose total register of theindividnal adding keys used in the operation or said store.

Another object of the invention is to pro vide a machine of thecharacter described which in addition to transferrins and c0n1- biningsaid totals will set back the adding machine, or adding key to zero sothat it can be re-used by other customers.

i/Vith the above and other objects view this invention has particularrelation to certain novel features of construction opera, tion andarrangement of parts, example of which is given in this specific tionand illustrated in the accompanying drawings, wherein:

ence designate similar parts in each or 0 finance the 1 designates thecascam shaft is fastened cam shaft carries a plurality oi spaced cams 7and it has a central here 8 through which the release rod 9 works. Theouter end of this rod is re duced and extended through the knob and isformed with a push button 10 which works in a socket 11 the outer end ofsaid knob. A coil push spring 13 is interposed between the push end or"-the shaft 2 and is confined within the knob The inner end of the releaserod 9 is formed into a release keylt. This rod is normally lockedagainst operation by means of the sectional spring! seated plnngers itwhich are seated in the socket 16 in, the block i and wo through alignedbearings and release rod. The each plunger is equal in nness of the walla whi works so th t is in alignn will i length to the cam shaft th whensaid min with said against operatf button and the opposing oration tothe plungers 15.

The inner end of the rod 18 carries the pivoted dogs 21 which areactuated by the (ey 14, when in co-acting relation therewith depress theplungers 20 into releasing position and at the same time the plungers 15are similarly released by the key 19, so that the interlocking shafts 2and 17 are free to turn. 7

The key is equipped with an adding mechanism which will nowbe'described:-rotatably mounted on the shaft 22 are a pluralit of rotaryunits each complete unit consisting of the ratchet wheel 26, the starwheel 23, the counter disc 24, and the stop lug 25, arranged in theorder stated, Transfer bars 27 are slidably mounted on the bearing shaft28 and one end of each bar is formed into a dog, said dogs coacting withthe corresponding aligned ratchet wheels 26.

It is contemplated that the counting discs 24 will be rotated bysuitable adjustable segments, (not shown) which work through the slots29 of the casing 1, in mesh with the star wheels 23. Each counting dischas the numerals from 0 to 9 thereon which come successively before thealigned windows 30 of the casing 1, as

the discs are rotated, as shown in Figures 2 and 5. Any number ofcounting discs may be used, depending upon the required capacity, orrange of the adding key. As shown five discs are disclosed. The firstregisters units or cents, the next registers tens or dimes, and so on,the amount indicated on any disc being ten times the correspondingamount indicated by the next receding disc of a lower denomination. Wile any disc is being rotated the corresponding transfer bar is drivenforwardly. carrying its dog out of the range of the aligned ratchetwheel until said disc has performed nine tenths of a complete rotation,that is, has counted tonine, and then said dog will engage with andactuate the ratchet wheel 26 of the next unit. to accomplish apartial(one tenth) rotation of the counting disc of the next higherdenomination and transfer the amount indicated by the next partialrotation of the former disc, to the latter.

In order to bring this action about oscillating levers 30' are mountedon the bearing rod 31 and at their free ends-are .pivoted to therespective dogs 27. These levers have the offset lugs 32- and thecorresponding cams 7 work against said lugs, and drive the levers andthe corresponding transfer bars 27 forwardly, and the levers arereturned by the tension of the coil springs 33. \Vhen the transfer barsare driven forwardly the shoulder 34 of each dog rides upon the adjacentend of the pawl 35 to hold the dog of said bar out of engagement withthe aligned ratchet 26. The pawls 35 are mounted on the bearing rod 36and are aligned with the stop lugs 25, and held yielding thereagainst bymeans of the tension spring 3 When a counting disc has accomplished ninetenths of a revolution the sloping side of the lug 25 pushes back,orret-racts, the corresponding pawl 35 and thereupon the shoulder 34, ofthe corresponding bar 27, is pulled down into the notch 38 of the pawl35 and the dog of said bar 27 then engages with the ratchet wheel 26 andupon the next backwardmovement of said bar the ratchet, and thecorresponding countin disc is turned one tenth of a rotation tfius ineffect transferring the amount counted by the preceding counter to it. Apull spring 39 is attached, at one end, to each bar 27 and .at "itsother end to the rod '36 and is ef fective to hold the shoulder 34against the adjacent end of the corresponding pawl 35, and to cause itto drop into the notch 38 when said pawl is retracted,

As the bar moves backwardly to effect this partial rotation of saidratchet wheel the shoulder 34 rides up out of the notch 38 and thelug 25havin passed the pawl 35 said pawl drops in behind said lug, actingunder the influence of the s ring 37, so that the dog of said bar 27 wilthereafter be held out of engagement with the aligned ratchet until thecorresponding pawl 35 is.

again retracted, as hereinbefore explained.

From the foregoing it will appear that each counter disc, in effect,adds one for each partial rotation up to nine, and with the tenthpartial rotation the amount added by it is transferred to the nextsucceeding counter disc of a higher denomination.

\Vhen the adding key is not in operation the slots 29 are closed by asliding shutter 40 which works within the casing 1 and partiallysurrounds the counting units forming the adding mechanism. This shutterhas the transverse slots 41 out therethrough and it is actuated by thelever 42. This lever is pivoted to the bearing block 43, confined withinthe casing 1. One end of the lever is pivoted to the shutter and itsother end rides on the cam 44 which is fastened on the shaft 2.

\Vhcn the adding key is inserted into the mechanism with whic it worksand the neatoe and operate the corresponding star wheels 23, and thensaid cam 44 again actuates said lever to again shift the shutter toclose said slots 29 and thus protect the counting mech anism againstinterference.

his to be understood that the mechanical adding key hereinbeforedescribed is priinarily designed to be used in connection with ourmechanical-store described in the application for United States LettersPatent hereinbefore referred to. 8

When a customer enters. the store he procures said key and by its usegains access to the goods and as the purchases are made the total costof the articles purchased is registered by said key. The key is thenreturned to the cashierand the price, registered by the key, is paid tothe cashier. A register of said price must be made and the key must beset back to zero so that it can be delivered toanother customer for use.It

' is obvious that a number of these keys -Will be necessary toaccommodate all customers.

A machine for totaling the registers of the keys used and for settingsaid keys back to zero will be necessary for conducting the businesswith dispatch. Such a machine will now be described The numeral refersto the casing which is formed with a pocket, or keyway 4-6 therein toreceive the mechanical adding key, heneinbefore described. When this keyis inserted its shaft 2 will align with the crank shaft d7, which isrotatablein suitable bean ings in the casing 45 and whose outer end hasthe crank 48 by means of which it may be turned. When in operativeposition the shafts 2 and 47 are released for rotation and clutchedtogether by means of a mechanism disclosed in Figure 8 and hereinbeforedescribed. The crank shaft 47 has a spur gear 49 fixed thereon whichdrives a train of spur gears 50, 51 and 52, the latter of which is fixedon the counter shaft 53. The gears 50 and 51 rotate on suitable spindles54- and 55 carried by the web 56, and this web is formed with bearingsin which the respective shafts 47 and 53 rotate. The shaft 47, as it isturned will rotate the shaft 2 and will also rotate the shaft 53 in theopposite direction.

The inner end of the shaft 4:? has a disc 57 fixed thereon, whose innerface is formed with a cam-shaped groove 58 in which the roller 59 runs.This rolleris carried by the link 60 one end of which has a long bearing61 to receive the hub of the disc 57 and the other end of which ispivoted to the upper end of the arm 62. The lower end of this arm isfixed to the frame of an adding mechanism 63 which totals the sumsindicated by the mechanical adding keys. In other words the amountscarried by said adding keys are transferred to the adding mechanism 63and the totals thereby registered.

The mechanical construction and operation of this totaling machine 63are similar to the mechanism of the key shown in Figures 5 to 8,inclusive, and will not be further described in detail.

End brackets ea, b4: have their lower ends formed into bearings 65, 65in which the I shaft 53 works, and one of these brackets is extendedforming the arm 66 whose free end has the spur gear wheel 67 rotatablym0unted thereon.

The upper ends of these brackets 64 are formed with aligned bearings 68,68 in which the shaft 69 rotates. Keyed on one end of the shaft 69 thereis a segmental rack member 70, and fixed thereon, between the bear-.ings 68 there is slotted cage 71f Loosely mounted on the shaft 69 thereare the segmental rack members 72, each composed of wings 73 and 74having gear toothed margins. These rack members 72 work through theslots 75 of said cage. A pair of pull springs 76 are attached to eachwing 7d, at one end, and at their other ends these springs are attachedto said cage. Each wing 73 has an arcuate slot 77 therethrough, formingbearings, which move on the bearing rod 7 8 which is anchored in, andextends transversely through, the cage.

@ne of the bearings 65 is formed with a projection 79, formingintegrally therewith, and a screw 80 is threaded therethrough, formingan adjustable stop, which is arranged opposite the abutment 81 whichstands up from the bottom of the casin 45. A pull spring 82 is attachedat one end or the projection 79, and at its other end it is fastened tothe casing 45.

An arm 83 is formed with a bearing 84 at one end, which works on theshaft 69, and its other end has a bearing pin 85 which projectslaterally through an oblong bearing slot 86 in the link 60.

Vlhen the crank -8 is turned the shaft 4:7 rotates the shaft 2 and thecam 44 rides out from under the end of the lever 42. Thereupon thepressure of the push spring 87 actuates the shutter 40 to align theslots 41 thereof with the slots 29 of the casing 1, so that thesegmental wings 73 may work through said slots into mesh with the starwheels 23 of the adding key. At the same time the cams 7 operate,through the add-- ing key mechanism described, to carry the bars 27 outof engagement with the ratchet wheels 26 to permit their reverserotation until they are stopped by the contact of the lugs 25 againstthe corresponding opposing dogs 35, in which position the zeros of the,counting discs 24 will align behind the 'the star wheels 23 with thecorresponding star wheels 23.

windows 30 and the adding key will then be set back for use by anothercustomer. As the link 60 moves under the influence of the cam groove 58the frame 63 is partially elevated causing the star wheels 23 toapproach the opposing segmental wings 74 with which they are designed tomesh, and the brackets 64 move with said link being swung around ontheir shaft 69 under the influence'of the pull spring 82, until thewings 7 3 are in position to mesh with the star wheels 23, at whichpoint the stop 80.

contacts against the abutment 81, as shown in Figure 3. The segmentalrack 88 has in the meantime moved into position to mesh with the rackmember 7 O and the further movement of the link 60 will further elevatethe frame 63 and bring the star wheels 23' into position to mesh withthe rack teeth of the wings 74. The further rotation of the shaft 47will now operate, through the rack 88, to rotate the member and theshaft 69 to which it is fixed, and the rack teeth of the wings 73 willmesh with and rotate the star wheels 23, of the addin key, reversely,until they are carried back to Zero and stopped, as above explained.Some ofi these star wheels will be stopped before the others, thisdepending on their respective positions when the adding key is insertedin the socket 46, and the springs 76 of the corresponding segments, alsostopped, will yield to permitthe others to move on until all of saidstar wheels 23, and the counter discs 2a are returned to zero position.

The wings 73 and 74 have a corresponding number of teeth. The. lattermesh with when the former mesh The numerals carried by the counterwheels 24 are arranged reversely with respect to the arrangement of thenumerals of the counter wheels 24 so that as the latter are turnedbackwardly the former will be turned forwardly with the result that thenumbers taken off of the adding key will be totaled onto the addingmechanism 63.

The continued rotation of the shaft 4:7 will operate through the camgroove 58 to move the link 60 backwardl which in turn will operatethrough the arm 62 to lower the adding mechanism 63 out of operativeconnection with the wings 7 4, and as said link 60 moves on backWa-rdlyit will operate through the link 83 to swing the brackets 64, 64backwardly and release the wings 73 from the star wheels of the addingkey. The pull of the springs 7 6 will then bring the segments '72 backin alignment in their original positions, relative to the cage 71.

The rack segment 89, fixed on the shaft 47 is now in position tointermesh with the near 67 and as the shaft 47 continues to rotate therotation of said gear is reversed, thus reversing the movement of therack member 70 and restoring the cage 71, and the segments carriedtherein, to original, or startmg position.

The adding key may then be removed, and another inserted and theoperation repeated. The sums indicated by the adding keys will thus betransferred to and totaled on the adder 63.
